FAQs about MRc4 :

Is the default average recycled content value of 25% for steel still allowed?

Can site materials, such as soil, be included in the MR credit calculations?

Are there recycled content claims that I should be wary of?

Can I count FSC-certified MDF toward both MRc4 and MRc7?

If I have one cut sheet that meets the LEED 2009 requirement to upload 20% of cut sheets by cost, for this credit, is that acceptable?

I have recycled content information for a product, but it doesn’t specify whether it is pre-consumer or post-consumer. What should I do?

The recycled content percentage on the product data sheet is given as a range. What should I do?

The manufacturer can't give me product-specific recycled content data, but they say that they fall within the national industry average. Can I use that?

NC-2009 MRc4:Recycled Content

MR4, MR5 Credit Default Percentage For Unavailable Information

The steel supplier for the structures contractor on our project has gone out of business and thus information regarding MR4 Recycled Content, and MR5 regional materials information is unavailable for material that has already been delivered and installed on the project. Is there a default percentage that can be used to address these credits? 

 

Thanks, 

Jack.

Hi Jack, Yes, there is a long-standing recycled content value for steel--it's covered in the FAQ section of this LEEDuser credit guidance--please check it out there. Not nearly as high as you would likely be able to get if you had the actual numbers, but sounds like you're stuck there. The regional materials info is a different story--that would have to specific to each location, so there is no default value there.
